DETAILED DESCRIPTION

[0014] The technical scheme of the utility model is further explained below in combination with the drawings and specific embodiments.

[0015] As Figure 1 , Figure 2 , Figure 3 Indicated, the utility model provides a kind of quick stripping device, including upper cover plate 1, upper mould 2 and lower mould 3, upper cover plate 1: as the top structure of entire device, its bottom is provided with upper mould 2.The top of upper cover plate 1 is provided with hydraulic telescopic device 101, for driving upper cover plate 1 and upper mould 2 to carry out lifting movement;Two sides are equipped with two groups of sliding sleeve 102, for with the sliding rod 304 on lower mould 3 sliding connection, ensure the stability of upper cover plate 1 in the process of lifting.

[0016] ‌Upper mould 2: install at the bottom of upper cover plate 1, its bottom equidistantly is equipped with injection head 202.The front of upper mould 2 is equipped with injection tube 201, and injection tube 201 is communicated with injection head 202, for into the mould cavity 301 of lower mould 3 with molten plastic.

[0017] ‌Lower mould 3: as the main component of forming injection molded part, its top equidistantly is provided with mould cavity 301.Cavity is opened in lower mould 3, and is equipped with air pump 302 and electric lifting seat 4.The top of electric lifting seat 4 is equipped with valve needle 401, and valve needle 401 is inserted into mould cavity 301 to close gas passage when injection, prevent plastic leakage;When stripping, lower and separate contact with mould cavity 301, so that the gas generated by air pump 302 can enter the inside of mould cavity 301, and blow out the injection molded part after forming.Lower mould 3 is equipped with two groups of mounting seat 303 on two sides, and the top of mounting seat 303 is fixedly equipped with sliding rod 304, and sliding rod 304 is slidably connected with the sliding sleeve 102 on the two sides of upper cover plate 1, to ensure the stability of upper cover plate 1 in the process of lifting.
